Harrov thought for a long time, but to no avail, finally sighed, looked at Theresa, and asked.

"Where's today's research?"

"Here, Teacher." Theresa respectfully handed over the stacked manuscript paper.

Harrov casually took a piece of parchment and looked at it, and although the various ideas put forward by these official wizards were full of loopholes, they were also enough to give him a little inspiration.

After all, this is exactly what he lacks most right now.

Harrov glanced at it in a row, then quickly tossed it aside, then picked up the next piece of parchment and looked at it.

After reading more than a dozen copies in a row, Harrov's patience slowly ran out.

Because the quality of the theories in this issue is so poor, many theories are not even based on facts at all, and they are just gratuitous fantasies.

What a waste of your time!

Forget it, let's read it first, in case you can find any inspiration?

Harrov shook his head, crushing on the last shred of hope, and picked up the very fine envelope that was left on the table.

"Next time, tell them to just bring the manuscript paper, and there is no need to mess with these messy decorations." Harrov said dissatisfiedly.

"Yes, teacher, I'll remind them." Theresa nodded hurriedly, and her heart became more and more disgusted with the wizard named Lynn from outside the wizarding lands, because the letter was taken from the other party.

"Huh?" After Harrov opened the envelope casually, the whole person was directly stunned.

Because the envelope was not full of research papers for magical theories, but an invitation.

[Dear legendary wizard Mr. Haroff.]

I heard that you are studying the laws of the movement of the stars and deciphering the secrets of gravity, space, and time, and I hereby invite you to join the [Arcane Society] to discuss the mysteries of the truth of the universe......]

Harrov's brows furrowed, he didn't know how many invitations to refuse every month for this kind of academic discussion organization, and now he took it directly in the research materials.

"I'm sorry, it's my fault, teacher, I should have reviewed it first." Theresa responded in a panic, this was her job, but because of the delay before, she took it directly.

"Arcane Society......" Harrov didn't throw the letter away, because he seemed to have heard the name somewhere. Who got this letter? ”

"It's a wizard named Lynn, the wizard from the Sea of Mists who came up with the planetary theory." Theresa said resentfully. "The megalomaniac also said that he brought three laws and a formula that will solve the problem you encountered."

"What about laws and formulas?" Harrov then asked.

This wizarding organization, since it can clearly put forward the theory of the planet and the law of free fall, then there is still something to prove it, and it doesn't hurt to see it!

Theresa choked and couldn't speak......

Fortunately, Harrov soon found the formulas and laws written down by Lynn on the back of the invitation.

[First Law: All planets orbit their stars in elliptical orbits, and the stars are at a certain focal point of the ellipse.] 】

Harrov's eyes swept over the first line, and then he nodded thoughtfully.

It is true that he also discovered this phenomenon in the process of studying the movement of the stars, but the question is why this is the case, according to his speculation, the gravitational field should be a perfect circle, and the star will also be in the center of the circle.

This is also one of the problems that has always bothered him.

So Harrov hurriedly looked down, but to his surprise, there was no explanation at all, but directly put forward the second and third laws.

[Second law: For any planet, the area swept by the line with the star is proportional to the time of motion, and the grazing velocity of the planet is constant.] 】

[The third law: the ratio of the quadratic of the semi-major axis of all planetary orbits to the quadratic of their orbital period is equal, and the ratio is only related to their orbital celestial bodies.] 】

Harrov's expression immediately became serious, because these were two completely new patterns that he had not yet discovered.

"Quick, get a pen and paper, I'm going to verify it." Harrov shouted loudly.

Could it be that these so-called laws are really useful for teachers? Theresa's heart was faintly uneasy, and she didn't understand why just three short sentences made Harrov, a legendary wizard, so out of shape.

Although confused, Theresa hurriedly took the pen and paper.

However, Harrov, who couldn't wait for a long time, directly used his magic power to write and draw in the air, and then took the data of those star maps and compared them one by one.

Theresa was so frightened that she didn't dare to come out, so she waited with a pen and paper and waited for hours.

When it was dark, Harrov stopped, looked at the orbital data of the stars suspended in mid-air, and muttered to himself.

"Yes, really yes!"

Harrov felt that he was closer to the truth than ever.

So, he looked at the end of the invitation.

There's just a short line of formulas there.

F=GMm/r^2

However, these operators ...... He couldn't read it at all!

What does the F stand for, and what is the G?

Haroff didn't know anything about these mathematical symbols from another world, and could only guess through the research he had just made, and he had a hunch that what he had been pursuing was within this short formula!

"What about Lynn? Where is he now? Harrov suddenly remembered the person who sent the letter, and asked eagerly, the other party must have understood the meaning of this formula.

"Old ...... Teacher, because it was too late yesterday, the wizard named Lynn had already gone back first...... As for now, he should be attending a seminar. Theresa replied in a slur that she didn't even dare to mention that she had deliberately stopped him at the door.

"I'll bring him right away!" Theresa hurriedly planned to go out and bring Lynn back.

As for the previous contradiction, she couldn't care about it so much.

Theresa knew very well that she was just a three-ring wizard with ordinary talent, and it was only after an academic paper that she gave Haroff some inspiration that she was appreciated and became an apprentice.

If this legendary wizard knew that he had made such a big mistake, then his current position would probably not be able to be maintained.

"No, it's too slow, I'd better go myself." As soon as Harrov's mind moved, the messy research manuscripts in the room were organized and gathered in his hands, and then flew straight out of the wide open window.
